Leers raient. Patented Feb. 17, 1914.

Application filed November 26, 1913. Serial No. 803,263.

To all whom it may concern i B6 it kIlOWn that I, GUS MAJOR` KAISER,l acitizen of the United States, residing at New Yorkcity, in the county ofNew York and State of New York, have invented new and usefulImprovements in 'Safetyl-azors, of which the following is aspecification.

The eneral object of this invention is to refine tie construction ofsafety razors, in point of promoting the efficiency of the same and incheapness of manufacture. And to these ends the invention resides-in aflat, relatively rigid blade and a resilient shield adapted to beadjusted in relation tothe edges of the blade.

Other objects will appear and be better understood from that embodimentof my invention of which the following is a specification, referencebeing had to the accompanying drawings forming part hereof, in which:

Figure 1 is a perspective view of my improved razor. Fig. 2 is a sideview of the razor partly in elevation and partly in sec-- tion. Fig. 3'is a dissected perspective view 'of the elements forming the razor.

The razor,as shown in the drawings, con' sists of theC holder 5 and theblade (5. The holder 5 is formed of a plurality of members which includethe handle 7 the guard 8 and the blade retaining member 9.

r1`he blade 6 used in my improved razor is formed from a flat andrelatively rigid sheet of razor-steel, and While it is of sufficientthinness to admit of a minimum expense in manufacture, it issubstantially rigid for all purposes of shaving. In order that it may beespecially adapted to be used in my improved razor-holder, which will behereinafter-fully described, a centrally disposed perforation 10 isprovided in the blade; and so that the life of the blade may be doujbled, the usual double shaving-edge 11-11 is provided. p

The blade is carried, when in the holder 5, by the retainer 9, which maybe made of cast steel or any like material. While the inside length ofthe retainer 9 and the length of the blade are of the same dimensions,the Width of the retainer is narrowed so that the edges of the blade mayproject beyond the edges of the retainer. A substantially long stem 12is centrally positioned on theJ inner face of the retainer and over thisis adapted to tit the perforation 10 of the blade, As only one stem isused,

. it Would seem obvious that the blade would have angular lateralmovement and to prevent this, the corners are provided with retaininglugs 13, which Contact with the opposite short ends of the blade and xthe blade in a steady position. It willbe seen that the retainer isprovided at each end with recesses or cut-away portions la which admitof iingerro'om when positioning the blade or removin the same from theholder.

Vhen the bla e is positionedon the retainer 9 and fitted within the sidelugs 13-,13, the-shield S is placed over theblade. This shield .issubstantially U-shaped and is preferably formed of light spring metal.The sides of the shield are fiared outwardly and the edges arepreferably fluted as at 15, so as to provide guards for the edges of theblade and recesses for the material removed from the face during theoperation of shaving. An opening 1G is centrallylocated in the top ofthe shield so that the stem 12 of the retainer may project therethrough.The handle 7 is provided with a screwthreaded bore 17, which is adaptedto be screw-threaded over the head 18 of the stud 1Q. It will be notedthat this head is relatively short and as only a portion of the bore 17is screw-threaded, the handle can be readily placedover the stem and afew turns will suiice to secure the parts together. As shown in Fig. 2,the lower portion A19 of the handle is narrowed so as to provide ashoulder 20. The part 19 is adapted to be inserted in the opening 1G andthe shoulder 2() will bear against the top of the shield; obviously, asthe handle 7 Yis turned so as to tighten the parts, the shield will beunder pressure and the fresult will be, that the guard ends 15 Will tendto separate, and reduce the cutting edges of the blade. Conversely, whenit is desired to increase the cutting edges, the pressure on the shieldis reduced. It will be seen by referring to Figs. 1 and 3 that theguards 15 are relatively longer than the sides of the shield andprovide, thereby, ears 21; it will also be noted that one edge 22 of thelugs 13 is oblique and is provided with a notch 23. Now, the normallateral distance between the ears 21 is less than the lateral distancebetween the remote edges ofthe vlugs 13, and upon the shield beingpositioned on the blade, the action of the oblique edges will be tospread the vsides of the shield apart, This spreading increases until'the llO ears 21 reach the notches 23 in the lugs, whereupon the shieldwill be sprung into position and by virtue of the tension in the shield,the guards 15, bearing I' the blade against the retaining member 9, Willsecurely hold the blade in a relatively rigid manner.

It is obvious that those skilled in the art may vary the details ofconstruction and arrangements of parts Without departing from the spiritof my invention, and therefore I do not wish to be limited to suchfeatures except as may be required by the claim. v

Whatis claimed as new is:

In a razor, the combination with a at blade, of a blade retaining memberhaving oppositely disposed lugs positioned at the ends thereof, the saidluvs having oblique sides provided With notces, and a resilient shieldprovided with laterally-extending guards having ears loca-ted atopposite ends7 the said ears being adapted to be sprung over the obliquesides of the lugs and into the notches upon the shield being placed inContact with the blade.

In testimony whereof I aiix my signature in presence of two'witnesses.

GUS MAJOR KAISER.
